N-(4-chloro-3-methyl-5-isoxazolyl)thieno[2,3-b]pyridine-3-sulfonamide was prepared by the method of Example 1(C) using NaH (0.16 g, 6.8 mmoles), THF (10 ml), 4-chloro-3-methyl-5-aminoisoxazole (0.36 g, 2.7 mmoles) and thieno[2,3-b]pyridine-3-sulfonyl chloride (0.70 g, 3.0 mmoles) to provide 0.86 g (96%) of the title compound as a tan solid. Recrystallization of 56 mg from EtOAc/hexanes provided 43 mg of a light tan solid, m.p. 176-177° C.
